Comparison of Adhesive (Bonding Agents) Used in Dentistry

As we enter the new millennium, we find a meteoric rise in the use of bonded composite restorations with immense success. To satisfy the growing esthetic demands of today's dental patients, improvements in materials and procedures have been made to make it possible to reproduce the natural teeth with direct and indirect esthetic restorations. Esthetic techniques involve a bonding step to ensure durability and reliability. The ideal bonding system should be:1. Biocompatible2. Bond indifferently to enamel and dentin3. Have sufficient strength to resist failure as a result of masticatory forces4. Have mechanical properties close to those of tooth structures5. Be resistant to degradation in the oral environment6. compensate for the polymerization shrinkage of the composite and7. Easy to use for the clinician.
